Solver, Web Services-based Distributed Computing

With developing and popularity of the computer and network technology,how to make better use of existing networks and share resources and play fully the overall efficiency of computer networks, which becomes one of the important issues for people concerning about and exploring. At present, people have developed a number of Web-based distributed computing systems, but at the same time, they have their own shortcomings respectively. Web services are not mature enough, but it is developing rapidly, which use a platform-neutral criteria (such as HTTP and XML), when Web Servicers are running, users do not need to know to the service mechanism, just know the services, but it can be used. So long as the service requester and service providers are connected by the Internet, it has nothing to do with the platform. The subject has given a distributed computing system of Web-based services.In the article we have analyzed firstly the research of distributed computing system based on Web services, the distributed system technology, environment and distributed computing major technology, and then given a system of distributed computing solver based on Web services, WS-DCS module model, it includs WS-DCS module's structural approach and WS-DCS module's computation model, Between mathematical expression tree and DOM transformation, it includs Mathex-DOM project objective, constitution plan and transformation predicate law design. Finally, we have given a simplified model of the system and the realization of simplified model system. The design of the system is to make fully use of network hardware and software resources on the network solver, and resolve the local computer can not solve the problem of equality constraints through a number of co-ordination. So we can use all forms of network services provided by a variety of the network computing resources to solve the problem that local computer software can not solve effectively.
